The ancient climatic evolution characteristic reflected by carbon and oxygen isotopes of carbonate in the ancient barrier lacustrine deposits,Diexi,Minjiang River;

Based on hydrochemistry,REE,carbon and oxygen isotope analyzing,possible leakage way of the Air-Cushioned Surge Chamber is studied in the Xiaotiandu power-station.

In order to know the formation surroundings of the Ordovician dolostone that is Lower Paleozoic reservoir of natural gas in the Ordos Basin,the relationship between its genetic type and carbon and oxygen isotope is studied.

Based on the measurement of the formation age,and the carbon and oxygen isotope composition of calcite collected at different sites of fissures in tunnel PD?16 at a dam area,southwesten China,and combining specific hydrogeologic conditions of the dam area,authors have determined the period of karst development in the studied stream area,and paleoclimatic conditions at that tim

C-O isotope composition of dawsonite and its implication on the fluid origin in Wuerxun sag,Hailaer basin,China;

Based on the core observation and description,the carbon and oxygen isotopes of calcite filled in fissures were analysed.

Based on the study on carbon and oxygen isotopes geochemistry of the lithlogical assemblage of Devonian, the sediments of the Devonian Fengxian-Taibai basin are divided into normal sediments and thermal sediments.

Functional relationship exists among carbon and oxygen isotopes of lacustrine deposits, elevation and mean annual temperature in the Tibetan Plateau.
